[0033] With the development of virtual reality (VR) technology, the way users interact with the digital world has also changed dramatically. There are two ways to install the speakers of existing VR devices. The first is to install them directly in the VR device. Although it is convenient for users to use, its installation structure is complicated and limited, and the sound effect is not good. The second is to connect the VR device externally. Although it increases the flexibility of users wearing speakers, it increases the weight of the head and reduces the user's immersion.
[0034] In view of this, an embodiment of the present application provides a VR head-mounted display device to improve the sound quality of the VR head-mounted display device when the user wears the VR head-mounted display device, giving the user a deeper sense of immersion.
[0035] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of the first VR head display device provided in an embodiment of the present application.
[0036] The VR head display device comprises: a head display device, a speaker component, and a shell component;
[0037] The head-mounted display device is connected to the speaker assembly via a shell assembly, which includes a first shell 1 for mounting the head-mounted display device, a second shell 2 for mounting the speaker assembly, and a connector for connecting the first shell 1 and the second shell 2; a groove is provided inside the second shell 2 for placing the speaker assembly.
[0038] In the embodiment of the present application, the head display device is the main part of the VR head display device, which is used to realize the VR display function. In the embodiment of the present application, the head display device includes a display screen, lenses, a processor, etc.
[0039] The speaker assembly is the sound unit of the VR headset device, which mainly includes multiple digital speakers composed of a driver chip and a sound unit array.
[0040] The speaker assembly is used to provide audio data to the user when the VR head display device reads multimedia data. The pixel sound unit array is a rectangular array, and the digital speaker is a rectangular structure with a size of 12*18mm and a thickness of 3mm.
[0041] In actual application, the processor in the head display device performs DSR (digital sound reconstruction) processing on the multimedia data to generate a pulse control signal and sends it to the multiple digital speakers. The digital speakers receive the pulse control signal and send the multi-channel quantized digital pulse signal to each sound pixel unit; each sound pixel unit converts the digital pulse signal into an acoustic pulse signal for output; the M*N cascaded array of sound pixel units on the digital speaker generate sound waves that are superimposed on each other to achieve sound.
[0042] For further information, please refer to Figure 2 , Figure 2 A schematic diagram of the structure of a digital speaker provided in an embodiment of the present application.
[0043] like Figure 2 As shown, Figure 2 It includes a pixel sound unit array 201 and a driving chip 202.
[0044] like Figure 2 As shown, the number of driving chips 202 is the same as the number of pixel sound unit arrays 201, and the driving chips 202 correspond to the pixel sound unit arrays 201 one-to-one, or one driving chip 202 corresponds to multiple pixel sound unit arrays 201, so that one driving chip 202 drives multiple pixel sound unit arrays 201 to make sound.
[0045] In an optional implementation of the present application, the digital speaker in the digital speaker headset may be one or more digital speakers. When there is only one digital speaker, the driving chip 202 and the pixel sound unit array 201 may be arranged in a rectangle.
[0046] Furthermore, in order to ensure that the speaker assembly can bring a deeper sense of immersion to the user, the groove arranged inside the second shell 2 includes a plurality of installation grooves, the number of the installation grooves is consistent with the number of the digital speakers, and the installation grooves are rotatably connected to the second shell 2.
[0047] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the internal structure of the second shell provided in an embodiment of the present application.
[0048] like Figure 3 As shown, Figure 3The digital speaker 31 includes: a second housing 2, a mounting slot 31, a connecting piece 32, and a digital speaker 33.
[0049] The connecting member 32 is used to connect the mounting groove 31 and the second housing 2 , and the digital speaker 33 is installed in the mounting groove 31 .
[0050] In actual application, the angle between each digital speaker 33 can be adjusted by adjusting the angle of the installation groove 31, so that after the user wears the VR head display device, the digital speaker 33 installed in the second shell 2 can face the human ear.
[0051] In an optional implementation of the present application, the connecting member 32 may adopt a connection structure of a universal shaft or a universal ball, or may adopt other structures that can cause the mounting groove 31 to deflect at a certain angle, and the present application does not impose any limitation on this.
[0052] For further information, please refer to Figure 4 , Figure 4 A schematic diagram of a digital speaker arrangement structure provided in an embodiment of the present application.
[0053] Figure 4 The device includes a digital speaker 33 , a second housing 2 , and a human ear 41 .
[0054] In actual application, users of VR head-mounted display devices and related personnel who manufacture VR head-mounted display devices can adjust the angles between the digital speakers 33 so that the sound holes of the digital speakers 33 located at different positions are facing the human ears 41, thereby enabling the VR head-mounted display device to bring better audio experience to the user and enhance the immersive feeling of the user when wearing the VR head-mounted display device.
[0055] In order to enable the digital speakers 33 to cover the human ears 41 , the installation slots 31 may be arranged in a circular shape or in a rectangular shape, so that the digital speakers 33 installed in the installation slots 31 may also be arranged in a circular shape or in a rectangular shape.
[0056] In order to facilitate users to wear the VR head display device, the first shell 1 on which the head display device is installed and the second shell 2 on which the speaker assembly is installed can be connected by a connector.
[0057] In an optional embodiment of the present application, the connecting member may be as follows: Figure 1 The connecting strap 3 shown, or the hollow helmet composed of a plurality of retractable connecting rods, allows the user to adjust the length of the connecting strap 3 or the size of the hollow helmet according to his or her head circumference.
[0058] When the connecting member is a connecting belt 3, one end of the connecting belt 3 is fixed to a first fixing position 4 of the first shell 1, and the other end of the connecting belt 3 is fixed to a second fixing position 5 of the first shell 1, and the first fixing position 4 and the second fixing position 5 are respectively located on both sides of the outer side wall of the head display device, wherein the second shell 2 is mounted on the connecting belt 3.
[0059] In an optional embodiment of the present application, considering the storage space of the VR head display device, the connecting belt 3 and the second shell 2 can also be connected through a storage structure, please refer to Figure 5 , Figure 5 A schematic diagram of the structure of a second VR head display device provided in an embodiment of the present application.
[0060] like Figure 5 As shown, Figure 5 The device includes a second shell 2, a connecting belt 3, and a storage structure: a first connecting structure 51, a second connecting structure 52, and a rotating shaft 53.
[0061] The first connection structure 51 is fixed on the connection belt 3 , one end of the second connection structure 52 is connected to the second housing 2 , and the other end of the second connection structure 52 is connected to the first connection structure 51 via a rotating shaft 53 .
[0062] When the VR head display device is in an idle state, the user rotates the second connection structure 52 so that the second connection structure 52 overlaps with the first connection structure 51, thereby reducing the space occupied by the VR head display device in the idle state.
[0063] Furthermore, considering that the rotating shaft 53 may become loose after long-term use, the second connecting structure 52 may not be able to overlap with the first connecting structure 51 when stored. The first connecting structure 51 and the second connecting structure 52 are also provided with a snap structure to enable the second connecting structure 52 to overlap with the first connecting structure 51 when stored.
[0064] When the user wears the VR head display device, the user can rotate the second connection structure 52 so that the first connection structure 51 and the second connection structure 52 are at a certain angle, so that the digital speaker installed in the second shell 2 is facing the human ear.
[0065] Furthermore, considering that the length of the first connecting structure 51 and the second connecting structure 52 may not match the position of the user's ear, causing the digital speaker installed in the second shell 2 to be unable to face the human ear, the first connecting structure 51 and the second connecting structure 52 may be retractable structures. In actual application, the user can adjust the length of the first connecting structure 51 and the second connecting structure 52 so that after the second connecting structure 52 is rotated, the digital speaker in the second shell 2 connected to the second connecting structure 52 faces the human ear.
[0066] When the connecting member is a hollow helmet structure, the second shell 2 is installed on the hollow helmet structure.
[0067] In another optional embodiment of the present application, when the user wears the VR head display device, it is considered that the speaker assembly in the second shell 2 may not be close to the human ear. Therefore, a rotating member is also installed on the connecting belt 3 or the hollow helmet to connect the second shell 2 with the connecting belt 3, or to connect the second shell 2 with the hollow helmet, so that after the user wears the VR head display device, the second shell 2 can be rotated and adjusted at a certain angle, so that the angle-adjusted speaker is close to the human ear.
[0068] In an optional embodiment of the present application, the rotating member may be a hinge structure that can rotate at a certain angle, or a universal shaft / ball structure, wherein, when the rotating member is a hinge structure, the axial direction of the rotating shaft of the hinge structure is parallel to the connecting belt 3. The present application does not limit this.
[0069] Furthermore, considering that after the user wears the VR head display device, the position of the second shell 2 on the connecting belt 3 or the hollow helmet may deviate from the position of the human ear.
[0070] The VR head display device also includes a sliding component, which includes: a fixed part and a sliding part with a sliding rail, and the track direction of the sliding rail is toward the head display device; wherein, the fixed part is installed on the connecting belt 3 or the hollow helmet, and the sliding component is installed on the second shell 2, and the second shell 2 is connected to the hollow helmet or the connecting belt 3 through the sliding component.
[0071] In actual application, a user wearing a VR head display device can adjust the position of the second shell 2 along the slide rail according to the actual position of the human ear, so that the second shell 2 is adapted to the human ear.
[0072] Further, similar to the case where the connecting member is a connecting belt, in the case where the connecting member is a hollow helmet structure, the second shell 2 and the hollow helmet structure can also be connected based on a similar Figure 5The first connecting structure 51, the second connecting structure 52 and the rotating shaft 53 are connected. For related details, please refer to Figure 5 The introduction is enough and I will not go into details here.
[0073] To sum up, the VR head display device provided by the utility model arranges multiple digital speakers along the circumference of the human ear, so that the digital speakers can face the human ear, thereby improving the immersive experience of the user when wearing the VR head display device.
[0074] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
[0075] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
